Radio signal transmission system including a plurality of transmitters
for transmitting a common signal
A single data signal is transmitted by two transmitters to two radio zones
having an overlapping zone therebetween. The data signal is frequency or
phase modulated and is mixed in the transmitters with RF carrier waves of
equal frequency. The data signal to one of the transmitters is delayed
between 5.degree. and 50.degree. with respect to the original data signal
to provide a phase difference between the transmitted signals.
